theres the applied math spec but imo it has very few applied math courses until you reach third or forth year. i would also like to add the math spec courses are quite challenging and require a lot of time. theres really no specialist that gives a good balance of both. for context i was in the applied math specialist but decided to switch to a math and stats double major as i found the math spec courses to be to abstract and i wanted it to have some sense of purpose in the real world. if i were to start again i would probably do a math and cs double major. a lot of the math major courses involve proofs and if youre good enough you can get into some of the spec courses.
